Osceola County firefighters quickly put the fire out, but 24 units in one of the recently opened buildings were all destroyed. Investigators said they have no doubt lightning is what sparked the flames.

"We did have confirmation of an explosion, which is what power does," said Deputy Fire Chief Danny McAvoy. "The power and the lightning that explodes caused the fire. Then all the faculties internal went off. The alarms and strobes and stuff."

Firefighters said the roof collapsed to the first floor.

"Everything collapsed. Everything internal has collapsed to the bottom floor. I don't see a whole lot of salvageable things here. There may be, but it doesn't look like there's going to be a whole lot of things that are left," said McAvoy.

Venus Price lives in a building nearby and said she could hear the huge boom.

"When it had struck, when it started to, it burned for about 30 minutes in one area," Price said. "And then the whole thing went up in smoke."

Fire crews aren't clearing the scene until Wednesday morning to make sure the fire doesn't spark up again.

"Everything collapsed. Everything internal has collapsed to the bottom floor. I don't see a whole lot of salvageable things here," McAvoy said. "There may be, but it doesn't look like there's going to be a whole lot of things that are left."

No one was injured. Officials said the displaced residents will likely be able to move into another one of the apartment buildings that was not damaged during the fire.

Officials said Wednesday that once the permits are approved the building will be demolished.
